AT&T produces video encryptor -- is it clipper based?

I just saw a story go by on the dow jones wire saying that AT&T had developed a "comprehensive security system for commercial information services". It is said to be an encryption system developed jointly by Bell Labs and VLSI, and its intedned for set-top boxes and "the internet". VLSI was one of the contractors on Clipper. Anyone know if this is an "escrowed" system? Anyone know any other details? Perry
